In 2015, Bristol Harbor Group, Inc. (BHGI) was tasked through an Indefinite Delivery/Indefinite Quantity (IDIQ) contract with the U.S. Army Corps of Engineers (USACE), Philadelphia District, Marine Design Center (MDC) to develop a detailed level structural design for the construction of the USACE’s Quad Cities Crane Barge. A SeaTrax Model S144 was incorporated into the design. Drawings were reviewed and approved by the American Bureau of Shipping (ABS). BHGI’s specialty subcontractor, Ariston Technologies, performed finite element analyses on the crane and barge combination. The analysis was based on loads generated by the project lifts. A longitudinal strength report, structural weight and CG estimate, damage stability report and spud well strength report and calculations were developed. The work included submissions to ABS, including the results of the finite element analysis.
In 2016, BHGI was tasked again by the USACE to support MDC in the design of several systems for the barge. Specifically, this second task order covered detail level design of the ventilation, heating and air-conditioning systems. Most interestingly, this second task included the design of the cooling system for the generators utilizing remote mounted radiators. Much of the work for this task was performed by BHGI’s subcontractor, The Shearer Group, Inc., and drawings for the systems were reviewed with MDC and then sent to ABS for approval.
In 2018, per MDC’s direction, BHGI provided direct FEA support to Conrad Industries to confirm as built structure met ABS requirements.
